1. Modernism in education is based on using the scientific method to gather data and develop testable theories, with the assumption that reality can be objectively perceived. 2. Postmodernism challenges the idea of there being a single correct field of knowledge defined by scientific rules, and instead sees competing paradigms that can be considered simultaneously. 3. Continuing to view educational change only through the lens of modernism will prevent genuine conceptual change and breakthroughs from occurring.
